BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic container such as a compact.
[0002]
[Prior art]
Conventionally, as a compact cosmetic container, a container as shown in FIG. 8 has been widely used. The compact container includes a container main body 60 that stores cosmetics, a lid body 70 that covers the container main body 60, and an operation piece 80 that is attached to the front end portion of the container main body 60 so as to be movable forward and backward. Sometimes, the operating piece 80 is pressed and moved to the back side, thereby lifting the front end portion of the lid body 70, thereby providing the engaging protrusion 61 provided at the front end portion of the container body 60 and the front end portion of the lid body 70. The engagement with the engaging claw 71 is released. In such a cosmetic container, the operation piece 80 is formed small in consideration of the appearance and the like. Generally, the lateral width of the operation piece 80 is set to about 10 to 15 mm so that a young woman or the like can easily press it with a fingertip.
[0003]
However, when the operation piece 80 is small like the cosmetic container, an elderly woman or the like cannot reliably press the operation piece to open the lid. Therefore, the present applicant has already proposed a cosmetic container including an operation piece 90 having a wide width as shown in FIG. 9 instead of the operation piece 80 shown in FIG. 8 (see Patent Document 1). In the operation piece 90 shown in FIG. 9, the lower side of the drawing is the front side, and the spring piece 91 side is the back side, and the operation piece 90 is attached to the attachment recess of the container body (not shown).

[Problems to be solved by the invention]
However, in the cosmetic container of Patent Document 1, since the operation piece 90 is wide in the horizontal direction, the pressing portion with the finger to the operation piece 90 often comes off from the central portion of the operation piece 90. For example, when the right side portion of the operation piece 90 is pressed with a finger, the right side portion moves rearward (container main body side) larger than the left side portion, and the operation piece 90 is easily tilted. Therefore, the present inventor has investigated the cause. As a result, I found the following. That is, in order to return the operation piece 90 that has been pressed and moved rearward to the original position, a pair of left and right linear spring pieces 91 are provided on the rear side (container body side) of the operation piece 90. 90, the spring piece 91 is fixed at one base of the rear center portion of the operation piece 90, and the spring piece 91 extends from the center portion to the left and right obliquely rearward. Each tip is in contact with the inner surface of the mounting recess indicated by a two-dot chain line. The pressing force (arrow A) applied to the operation piece 90 is supported at one place at the base (center portion) of the spring piece 91 (arrow B). For this reason, when the pressing portion to the operation piece 90 is slightly disengaged from the central portion to either the left or right, the operation piece 90 is inclined with the root (center portion) of the spring piece 91 as the center. In addition, if the lateral width of the operation piece 90 is wide, the probability that the pressing portion to the operation piece 90 is disengaged from the center part to either the left or right is increased, and the frequency at which the operation piece 90 is tilted increases.
[0006]
The present invention has been made in view of such knowledge, and an object of the present invention is to provide a cosmetic container in which the operation piece is not inclined in the pressing operation of the operation piece.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a cosmetic container according to the present invention includes a container body, a lid that is hinged to the rear end of the container body and engages with the container body at the front end, and the front end of the container body. And a pair of left and right linear elastic bodies on the side of the container body of the operation piece. In the state aligned in the direction, the opposite base sides of the pair of left and right linear elastic bodies are fixed to the end surface of the operation piece on the container main body side, and the shape of the linear elastic body is changed from the fixed portion to the container main body. A base portion extending to the side, an intermediate portion extending laterally outward from the tip portion of the root portion, and a tip portion extending from the tip portion of the intermediate portion to the container body side are formed into a substantially crank shape, before the tip of the tip portion of a substantially crank-shaped elastic rod of the container body It is brought into contact by deflecting the substantially crank-shaped linear elastic body section, a configuration that is the movable back and forth in a state of being urged to the operating piece on the front side.
[0008]
That is, in the cosmetic container of the present invention, the root sides of the pair of left and right linear elastic bodies are opposed to each other, thereby keeping a distance between the root portions of the pair of left and right linear elastic bodies. For this reason, with respect to the pressing force with the finger on the operation piece, the operation piece is supported at two locations on both roots of a linear elastic body such as a linear spring piece. As a result, even if the pressing portion with the finger on the operation piece is slightly deviated to the left or right from the central portion, the biased pressing force is corrected by the spring action of the pair of left and right linear elastic bodies, and the operation piece There is no inclination.

This engaging protrusion 13 engages with an engaging claw 21 (see FIG. 1) formed at the front end of the lid 2.
[0012]
The operation piece 3 will be described in detail. As shown in FIG. 3, the operation piece 3 is formed in a substantially box shape having an open back surface composed of an upper plate 3a, a lower plate 3b, a front plate 3c, and both side plates 3d. Yes. And the linear spring piece 31 is formed in the state extended in the horizontal direction integrally in the notch recessed part of the right-and-left both ends edge of the lower board 3b of the operation piece 3. As shown in FIG. As shown in FIG. 4 (bottom view as viewed from the lower plate 3b), the linear spring piece 31 has a substantially crank shape including a root portion 31a, an intermediate portion 31b, and a tip portion 31c. The tip portion 31c slightly protrudes from the rear end edge of the lower plate 3b, and the tip thereof is sharply formed.
[0013]
In addition, the engaging claw portions 11 projecting from the left and right of the inner surface of the mounting recess of the container main body 1 are provided at the left and right symmetrical positions at the opening of the operation piece 3 having an open back surface and a substantially box shape (FIG. 2). A linear engaged portion 32 that engages with the lower plate 3b extends from the upper plate 3a to the lower plate 3b. Further, the front plate 3c of the operation piece 3 is formed in a curved surface in which the central portion gradually protrudes, and the central portion can be seen from the appearance. Further, on the lower surface of the upper plate 3 a of the operation piece 3, a guide portion 12 (see FIG. 2) protruding from the front end portion of the container body 1 when the operation piece 3 is advanced and retracted at a symmetrical position. Plate-shaped guide ribs 33 that slide on both side surfaces are formed. In addition, a notch recess for allowing an engaging claw 21 (see FIG. 1) protruding from a front end portion of the lid body 2 to be described later is formed at the rear of the center portion of the upper plate 3a.
[0014]
And in the state where the operation piece 3 is attached to the front end mounting recess of the container body 1, as shown in FIG. 5 (partially broken plan view of the main part of FIG. 1), the tip of each spring piece 31 is The container body 1 is in contact with the inner surface 1a of the front end mounting recess. Due to this contact, the spring piece 31 is slightly bent toward the front side, and an elastic force (arrow C) is applied to the spring piece 31 so that the operation piece 3 is always urged toward the front side. Yes. Further, the guide ribs 33 of the operation piece 3 slide on both side surfaces of the guide portion 12 of the container body 1 when the operation piece 3 is advanced and retracted. The piece 3 can be guided appropriately and can be moved backward, so that the lid can be opened reliably.
[0015]
As shown in FIG. 6 (a cross-sectional portion viewed from the direction of arrow D in FIG. 1), the lid 2 is detachably attached to the engagement protrusion 13 of the container body 1 at its front end. An engaging claw 21 that engages with is suspended. The front side portion of the engaging claw 21 is formed on a slope 21a that is inclined downward toward the back side.
[0016]
When the lid is opened, the operation piece 3 is pressed and retracted to the back side (right side in the drawing). Thereby, the rear surface 34 of the notch recess formed in the center portion of the upper plate 3 a of the operation piece 3 pushes up the engaging claw 21 while sliding on the slope 21 a on the near side of the engaging claw 21. As a result, the engagement between the engagement protrusion 13 of the container body 1 and the engagement claw 21 of the lid 2 is released, and the lid is opened as shown in FIG. At this time, even if the central portion of the operation piece 3 is not pressed, the operation piece 3 is not inclined.
[0017]
That is, in the cosmetic container, in the back side [container main body 1 side] of the operation piece 3, the root sides of the pair of left and right linear spring pieces 31 for biasing the operation piece 3 toward the front side are opposed to each other. Thus, a distance is provided between the root portions. For this reason, as shown in FIG. 4, the pressing force (arrow A) on the operation piece 3 is supported at two locations on both roots of the pair of left and right spring pieces 31 (arrow B ₁ , B _2). And when the press part to the operation piece 3 comes off from the center part, the biased pressing force (arrow A) is corrected by the spring action of the spring piece 31. As a result, the operation piece 3 is not inclined.
[0018]
Thus, according to the cosmetic container of this embodiment, a distance is provided between the root portion of the pair of left and right linear spring pieces 31 for biasing the operation piece 3 toward the front side. Therefore, even if the pressing portion with the finger to the operation piece 3 that is wide in the lateral direction is deviated from the center portion, the operation piece 3 is not inclined due to the correcting action.
[0019]
Note that the distance between the root portion of the pair of left and right spring pieces 31 is 10 mm (about the width of the fingertip) or more in that the operation piece 3 is more stable during the pressing operation. preferable.
[0020]
Next, examples will be described.
[0021]
[Example 1]
An operation piece 3 similar to that shown in FIG. 2 was injection-molded using ABS as a material. And the substantially crank-shaped spring piece 31 was as follows. That is, the cross section is a square of 1.2 mm × 1.2 mm, the protruding length of the root portion 31a (the length at the center of the cross section) is 2.0 mm, and the length of the intermediate portion 31b (the length at the center of the cross section). 9.0 mm, the length of the tip portion 31 c (the length at the center of the cross section) is 2.5 mm, the protruding length of the tip portion 31 c from the open rear surface of the operation piece 3 is 2.3 mm, and the pair of left and right spring pieces 31 The distance between the root portion and the root portion was 40.0 mm. And in the state which attached the said operation piece 3 to the container main body 1, the engagement nail | claw part 11 of the container main body 1 and the to-be-engaged part 32 of the operation piece 3 so that the front-end | tip of the operation piece 3 may bend 0.2 mm near side. And formed. The operation piece 3 had a lateral width of 67.0 mm, a height of 5.0 mm, a plate thickness of 1.2 mm, and a front curved surface having a radius of 210.0 mm.
[0022]
And when the operation piece 3 of Example 1 was attached to the container main body 1 and the pressing operation was performed, the operation piece 3 did not tilt even if the pressing portion was removed from the center portion. Moreover, even if the pressing force was small, the lid could be opened and there was no pain in the fingertips.
[0023]
【The invention's effect】
As described above, in the cosmetic container of the present invention, the pair of left and right linear elastic bodies for urging the operation piece toward the near side are aligned in the lateral direction and opposed to the container body side portion of the operation piece. Since the root side is fixedly formed, a distance is provided between the root portions of the pair of left and right elastic bodies. For this reason, even when a biased pressing force acts on the operation piece, it can be supported at two locations on both roots of the elastic body and can be corrected by the spring action of the linear elastic body. No tilting occurs on the operation piece. As a result, the lid can be reliably opened.
[0024]
Further, in the cosmetic container of the present invention, the operation piece is formed in a substantially box shape having an open back surface composed of an upper plate, a lower plate, a front plate, and both side plates, and the substantially crank-shaped linear elastic body. When the base side is fixed to the end surface of the lower plate on the container body side, and the central portion of the front plate is formed in a curved surface that gradually protrudes , the central portion of the front plate can be seen in appearance. The
[0025]
In particular, in the cosmetic container of the present invention, when the distance between the base portion of the pair of left and right elastic bodies is set to 10 mm or more, the operation piece is pressed during the pressing operation of the operation piece. Is more stable.
[0026]
Furthermore, in the cosmetic container according to the present invention, a pair of left and right guide portions are projected at a predetermined interval at the front end portion of the container body, and the left and right end portions of the operation piece on the container body side are respectively provided with the guide portions. When a guide rib is formed as a guide when the operation piece is moved back and forth by sliding on the side, the operation piece is guided and retracted backwards even if the pressing direction to the operation piece is oblique. The lid can be opened more reliably.
